What is a Bottling Plant Star Wheel
A star wheel is a precision machined rotating component used to index, space, and transfer bottles through key stages of a bottling line such as infeed, filling, rinsing, labelling, or discharge. The starshaped pockets engage individual bottles, holding them securely and guiding them smoothly through the process at high speed. This controlled movement is critical for maintaining line efficiency, accurate positioning, and minimising bottle damage or instability, especially in high throughput operations.
The Dotmar advantage: local manufacture, customisation, and reverse engineering
Dotmar’s capability to manufacture star wheels locally delivers significant advantages over imported alternatives. Local production reduces lead times, improves responsiveness, and minimises downtime when replacements or design adjustments are required.
Using 3D scanning and reverse engineering, Dotmar can accurately replicate existing star wheels—including legacy or imported designs—while also optimising geometry to suit specific bottle formats, speeds, or machine interfaces. This enables true application‑specific customisation, rather than relying on off‑the‑shelf components that may compromise performance.
By combining local machining expertise, material knowledge, and advanced digital measuring technologies, Dotmar provides UHMWPE Polystone M 7000 star wheels that offer:
- Precise fit and repeatability
- Rapid replacement or duplication
- Ongoing support for future machine modifications
- Reduced total cost of ownership compared to imported alternatives
This integrated approach ensures customers receive a high‑performance, purpose‑built star wheel that supports long‑term productivity and reliability in demanding bottling environments.
Material Choice: UHMWPE Polystone 7000
Star wheels manufactured from UHMWPE Polystone M 7000 are widely used in bottle and can manufacturing due to the following:
- Excellent wear resistance
- Low coefficient of friction
- Impact strength
- FDA-compliant material properties
These characteristics help ensure smooth bottle handling, reduced noise, long service life, and reliable performance in both dry and wet environments typical of bottling plants.
